Cyanate Ester Syntactic Foam 350°F Cure
Cuming Microwave Corporation manufactures toughened cyanate ester syntactic foam suitable for 350°F curing operations. This material in its uncured state is the consistency of wet snow. The material is ideal for encapsulating components, due to its low weight and controlled dielectric constant. Materials are available in both low loss versions as well as controlled loss versions. Typical insertion loss values for lossy versions are from 1 dB per inch to 15 dB per inch.
Typical out time is 3-4 weeks depending on ambient temperature. Typical 0°F storage is 6 months. A non-slump paste is also available for bonding operations of multiple blocks of foam. This material is effective in preventing resin flow into already cured blocks. Typical density range for the foam is 12-20 lbs. per cubic foot depending on application.
Cyanate Ester Syntactic Foam 250°F Cure
Cuming Microwave Corporation manufactures toughened cyanate ester syntactic foam suitable for 250°F curing operations. This material in its uncured state is the consistency of wet snow. The material is ideal for encapsulating components due to its low thermal shrinkage. Because the material is cured much lower in temperature than conventional 350°F cured materials many problems associated with CTE of dissimilar materials can be eliminated. Typical density range for the foam is 12-20 lbs. per cubic foot.
